16 Channel Audio Zone controller

The Redback Communicator is a paging system controller utilising the latest microprocessor circuitry that allows for both 100V line level or low level balanced line signals to be switched. Incredibly flexible and expandable, the Redback communicator is the result of many years development with direct feedback from pro sound contractors.Ideal for paging and background music (BGM) control in large scale PA systems up to 16 zones (expandable to 32 zones with the addition of a second A 4580), such as schools, factories, shopping centres, airports, hotels, sporting venues and large corporate buildings.The A 4580 is a central paging system control hub housing the switching circuitry. Background music is selectable on or off to any zone via the selection switches on the front panel.

When combined with the A 4660 paging console, each zone may be paged either individually or together with the use of the All-Call function. A “macro” function is also provided to enable the user to program a button for one touch operation of multiple zones. Up to 8 paging consoles can be connected across 4 circuits (max 2 per circuit).
